Modified asphalt waterproof roll for tunnel engineering

Abstract

The invention discloses a modified asphalt waterproof roll for tunnel engineering. The modified asphalt waterproof roll comprises a special roll, wherein a roller shaft is mounted inside the special roll; square supporting plates are mounted at the two ends of the roller shaft; a roll side bulge is arranged on the bottom surface of one side of the special roll; a roll side groove is formed in thebottom surface of the other side of the special roll; the special roll comprises a lining base layer, an anticorrosive layer, a buffer layer, a second isolating membrane, a surface waterproof layer, afireproof layer and a waterproof thick adhesive layer; the second isolating membrane is mounted above the waterproof thick adhesive layer; the buffer layer is mounted on the upper end surface of thesecond isolating membrane; the anticorrosive layer is mounted on the upper end surface of the buffer layer; the lining base layer is mounted on the upper end surface of the anticorrosive layer; the fireproof layer is mounted on the upper end surface of the lining base layer; the surface waterproof layer is mounted on the outer surface of the fireproof layer. The modified asphalt waterproof roll isstrong in waterproofness, has fireproof, cold-resistant and buffering performance and the like and is high in safety.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a modified asphalt waterproof coiled material for tunnel engineering. Background technique [0002] With the rapid development of social economy, asphalt waterproofing membrane refers to the roll material made of asphalt material, tire material and anti-adhesive material spread on the surface, also known as linoleum, which is often used for pasting waterproof layer. Asphalt waterproofing membrane refers to The most common ones are tire coiled materials and tireless coiled materials. Any roll material made of heavy paper or glass cloth, asbestos cloth, cotton and linen fabrics and other tire materials impregnated with petroleum asphalt is called tire coiled materials; asbestos, rubber Powder, etc. are mixed into the asphalt material, and the rolled material made by rolling is called a rolled roll, that is, a tireless roll. The cost of the bitumen waterproof rol...
